Chemical Structure

25038-32-8 Benzene, ethenyl-, polymer with 2-methyl-1,3-butadiene CAS 25038-32-8 chemical structure

Description

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

25038-32-8 Benzene, ethenyl-, polymer with 2-methyl-1,3-butadiene (CAS 25038-32-8), molecular formula C8H14C5H8 and molecular weight 178.32 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 25038-32-8 Benzene, ethenyl-, polymer with 2-methyl-1,3-butadiene (C8H14C5H8) is characterized by an organic framework. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

As a certified reference material (CRM), 25038-32-8 Benzene, ethenyl-, polymer with 2-methyl-1,3-butadiene meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
